From my experience working on it from time to time at Joyent, the parts that are implemented work pretty well on the lx brand in illumos. At the time, things like cgroups and namespaces were not implemented and there was no clear path to implement them. It’s kinda hard to participate in the docker or k8s ecosystem with such limitations.

I was hired at Joyent largely to work on bhyve so that Triton and Joyent’s public cloud had a way to run Linux VMs when full Linux compatibility was more important than the efficiency of zones/containers.
